Here's a treat for you PlayStation 3 owners. Rockman Complete Works will be coming to PSN this week for $5.99. This is the original PSX remake released in Japan, with a helpful navigation system, character and enemy bios, and an alternate arranged soundtrack. These were this was the same version of the game used for the Mega Man Anniversary Collection.
Since this comes under PSN's "Japanese Classics," a lot of the game's extra features will still remain Japanese. But of course, it's not necessary to know Japanese to enjoy the original Mega Man, unless seeing the name "Rockman" just blows your mind or something.

Hopefully more Complete Works titles will be coming along in short order too!
